METALLIC TAKE-UP SPOOL.

Specification of Letters Patent.

Patented 9ct. a, 31.910.

Application filed September 12, 1907. Serial No. 392,537.

To all whom it may concern:

Be it known that I, PETER WELIN, a citizen of the United States, residing at lVorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Metallic Take-Up Spool, of which the following is a specification.

This invention relates to a take-up spool for use on automatic musical instruments and players therefor.

The principal objects of the invention are to provide a light and inexpensive construction of such a nature that the ring on the end of the `music sheet can be readily attached to an integral hook on the drum of the spool, which is of such a nature as to be permanently fixed in position; to provide means whereby the device can be readily manufactured chiefly from drawn metal, in such a way that the metallic parts can be exceedingly thin so as to avoid excessive weight without sacrificing strength; to provide a convenient way of supporting the gearing and at the same time provide a brake wheel surface; and in the preferred form of the invention, to provide movable flanges which will be spring-pressed and will. be held in proper position so as to receive note sheets of different widths between them in accordance with their adjustments.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which,

Figure 1 is an elevation partly in section of one embodiment of the invention, Fig. 2 is a similar view showing another way in which the invention can be carried out. Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 1, and Fig. t is ai sectional view on the line 4 t of Fig. 1.

I will first describe the form of invention shown in Fig. 2. ln this form, a metallic drum 10 is provided with a perforation 11 near the center thereof, located in a depressed surface 12 and having` a hook 13 tending transversely of the drum but entirely within the cylindrical surface thereof. Preferably its outside surface is coincident with the surface of the drum so that it may assist in supporting thc note sheet.

This hook and depressed surface are formed integrally with the drum of the take-up spool` The spool is provided with a pair of flanges lt which, in the form shown in Fig. 2, are formed separate from the drum of drawn 'metal or the like and secured to the ends of the drum by forcing the flanges 141 thereof into the end of the drum. Beyond these flanges there are a pair of projecting reduced cylindrical ends 15 from the ends of which project the shaft or studs 16, such as are usually provided. These reduced portions are preferably formed of drawn metal separate from the drum and secured to the flanges 141 by being forced into the same. They extend through passagse in the frame of the tracker-box- On the end of one of them is mounted a disk 20, preferably integrally connected wit-h the reduced end and having a face 21 thereon serving as a brake wheel and adapted to be engaged by a brake 22 of any desired construction. This disk also serves another purpose, in that the gear 23 by which the take-up roll is driven, is secured to it and supported by it. ln this form of the invention, it `will be seen that the parts can be made mostly of drawn, pressed, or stamped out inet-al, and therefore the parts can be made very thin and of exceedingly light weight. In this form, also the parts are all secured together in fixed position without soldering, brazing or the like and after once being set up, there is no likelihood of their getting out of true.

In the form of the invention shown in Fig. 1, the same general principle is preserved and the parts so far described will not be referred to in detail but in this case the flanges or guides 1li() are movable longitudinally of the drum so that they may be adjusted to accommodate note sheets of different widths. ln order to provide for this, the flanges 150 of the reduced cylindrical ends 15 preferably are placed at a little distance back from the end of the drum and on each of these cylindrical ends is mounted to slide an adjusting member 30 which is hollow and through which passes the reduced end 15. It is provided with an enlarged cylindrical portion 31 adapted to lit over the end of the drum. It is at the inner end of this cylinder 3l that the flange 140 is located.

It Will be seen that the integral piece consisting of the guide piece 30, the cylindrical enlargement 31 and the flange 14() is movable to provide the necessary adjustment and that a chamber is provided in which is located a spring 32 for normally7 holding the flange at its outermost position.

In order to limit the position of the flange, the cylindrical member 15 is provided With a pin 83 and the guide piece 30 is provided with slanting surfaces 3a having slots 35 therein at different distances from the end of the guide. In the present instance two of these slots are connected with each other` by the slanting surfaces so that the guiding piece may be `pushed inwardly and the pin disengaged from its slot and then can be turned so that the pin Will move along the slanting surface until it reaches the next slot. In this Way, adjustment to accommodate any number of predetermined Widths of music sheets can be provided for, according` to the number of pins and slots. Both' ofthe flanges on the take-up spool are preferably constructed in the same manner.

IVhile I have illustrated and described t-Wo forms in Which the invention may be embodied, and described all parts of the device as made of metal, I am aware that many modications may be made in both of these forms, and that other materials may be used Without departing from the scope of the invention as expressed in the claims. Therefore, I do not Wish to be limited to the particular form shown and described, but

What I do claim is :d

l. A take-up spool comprising a metal drum for receiving a music-sheet, having a sunken surface near the center thereof, and a tongue integral With said drum extending from said sunken surface, said tongue being located entirely Within the cylindrical surface of the drum.

2. A take-up spool comprising a drawn metal drum for receiving a music sheet, having a sunken surface near the center thereof, a perforation through said surface, and a tongue projecting' over said perforation, said tongue being located entirely Within the cylindrical surface of the drum and having its outside surface coincident therewith.

3. A take-up spool comprising a drawn metal drum for receiving the music sheet, having an integral hook thereon near the center, metallic flanges on t-he ends of the drum, and reduced cylindrical portions at the ends of said drum secured to the drum.

4. A take-up spool comprising a metal drum having flanges thereon, reduced cylindrical port-ions at the end of the drum formed of drawn metal and secured to the drum, centering studs held by said reduced portions, an outer flange at the end of one reduced portion, and a. gear Wheel fastened to said flange.

5. A take-up spool comprising a drum, flanges thereon, cylindrical reduced portions at the ends of said drum, a disk at the end of one of said reduced portions having an inwardly extending face constituting a brake Wheel, and a gear Wheel secured to said disk.

(3. A take-up spool comprising a metal drum, reduced end portions secured thereto, a disk provided with a brake flange on one of said reduced portions, a gear Wheel fastened to said disk, and movably mounted flanges located on the ends of said drum.

7.
